MAX17048X / MAX17049X Evaluation Kits (WLP)
Evaluate: MAX17048X/MAX17049X in a WLP
General Description
The MAX17048X/MAX17049X evaluation kits (EV kits)
include the MAX17048X/MAX17049X EV kit and the
Maxim DS91230+ command module. Windows XPM-,
Windows VistaM-, and Windows 7-compatible software is
also available for use with the evaluation kit and can be
downloaded from www.maxim-ic.com/evkitsoftware.
The EV kits are fully assembled and tested surfacemount PCBs that evaluate the MAX17048X /MAX17049X
host or battery-side fuel gauge for 1-cell/2-cell lithiumion (Li+) batteries in handheld and portable equipment. The EV kits can be powered from a single battery
(MAX17048X) and configured to evaluate a single lithium
cell (MAX17048X) or from two lithium cells in series
(MAX17049X).

Quick Start
Required Equipment
• MAX17048X or MAX17049X EV kit
• +2.5V to +4.5V DC power supply or 1-cell battery
• DS91230 PicBrick board
• RJ12 6-pos/6-pos reverse modular cord
• Windows XP, Windows Vista, or Windows 7 PC
• USB port
Procedure
The EV kits are fully assembled and tested. Follow the
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
1) Connect the DS91230 board to a spare USB port on
the PC.
2) Connect the RJ12 cord between J2 on the DS91230
board and J1 on the MAX17048X/MAX17049X EV kit.
3) Verify that shunts are installed according to the
defaults listed in Table 1.
4) Connect the positive terminal of the power supply or
battery to the BAT+ PCB pad on the EV kit. Connect
the negative terminal of the power supply to the
BAT- PCB pad on the EV kit.

5)Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the MAX17048X or MAX17049X
EV kit software, MAX17048Rxx.ZIP/MAX17049Rxx.
ZIP. Save the EV kit software to a temporary folder
and uncompress the ZIP file.
6) Install the EV kit software on your computer by
running the SETUP.EXE program inside the temporary folder. The program files are copied and icons
are created in the Windows Start | Programs menu.
The software requires the .NET Framework 4. If you
are connected to the Internet, Windows automatically
locates the correct files and walks you through the
process. You can also download the Microsoft .NET
Framework 4 Client Profile (Standalone Installer)
and run that on your PC.
7) Start the MAX17048X/MAX17049X EV kit software by
opening its icon in the Start | Programs menu.
8) Load the default or custom battery model.

MAX17048X / MAX17049X Evaluation Kits (WLP)
Evaluate: MAX17048X/MAX17049X in a WLP
Detailed Description of Hardware
The MAX17048X /MAX17049X EV kits are fully assembled and tested surface-mount PCBs that evaluate
the MAX17048X/MAX17049X host or battery-side fuel
gauge for 1-cell/2-cell Li+ batteries in handheld and
portable equipment. The EV kits can be powered from a
single supply or battery with an input range of +2.5V to
+4.5V. The EV kits can be configured to evaluate a single
lithium cell (MAX17048X) or two lithium cells in series
(MAX17049X). Optional LDO U2 is provided to power
VIN when using a higher voltage 2-cell Li+ battery to
evaluate the MAX17049X.
Default Jumper Settings
The MAX17048X EV kit is set by default to evaluate 1-cell
Li+ batteries while the MAX17049X EV kit is set by default
to evaluate 2-cell Li+ batteries. LDO U2 is provided so
that only a single supply is needed to power the EV kit in
the case where a 2-cell battery is used.
When evaluating the MAX17048X, set jumper JU1 to pins
1-2 and remove any shunt installed on jumper JU2 to
bypass the LDO. When evaluating the MAX17049X, set
JU1 to pins 2-3 and install a shunt on JU2 to power VIN
from the LDO. See Tables 2 and 3 for JU1 and JU2 settings. When using a separate supply for VIN or evaluating
the MAX17048X, JU2 should be uninstalled to prevent
additional current drawn from the battery.
Detailed Description of Software
Splash Screen
The splash screen (Figure 1) allows you to choose one of
three distinct modes:
• Custom model with a physical MAX17048X/
MAX17049X. Custom models for the MAX17040–
MAX17044 can be used in this software provided you change the line Device = MAX1704x to
Device = MAX17048.
• Default model with a physical MAX17048X.
Warning: Using the default model normally results in
poor fuel-gauge performance. For good fuel-gauge
performance, it is recommended to always use a
model that is matched to the battery according to battery characterization.
• Demo mode with a MAX17048X log file.
• The MAX17049X EV kit software is also available for
download at www.maxim-ic.com/evkitsoftware.
Main Window
You can resize the left-right split in the window (Figure 2).
Most major functionality is available from the menu, but
some of these items should be observed early.
Currently Loaded Custom Battery Model
This group displays any custom model that has been
loaded onto the part by the software. If the device resets,
this model is automatically reloaded. If you are using the
default model, nothing is displayed here. Any changes to
the configuration file is not reloaded automatically.
Record Registers to Log File
This group displays the file path to which the software
is recording the registers. If this box is blank, no file is
being saved.
RCOMP Configuration
Enter a byte here and press the Write button to write it
to the device. This is not the same as writing the value
into the memory map because RCOMP is part of a larger
2-byte register.
If you have a custom model, you can also change the
temperature, which adjusts the MAX17048X for proper
temperature performance. Changing this value immediately calculates a new value of RCOMP and displays
it in the box. This value is not written to the device until
you press the Write button. A change to RCOMP is not
reflected in the temperature.

Memory Map
Notation used for name and address should be familiar
to C programmers with one small change. The memory
map lists:
• Register Name: A dot indicates that a single address
has multiple meanings. This is similar to how the
C firmware might access the bits.
• Memory Address: A colon indicates the 0-indexed
location, not the size of the bit field. A dash indicates
a range of values (e.g. 0x0C:0-4 is a 5-bit value, offset
0 bits at address 0x0C).
• Hex: The raw value as read directly from the device
• Value: A conversion of the raw hex value, usually with
units. Alert bit flags are blank when inactive, or show
text when they are alerting.
• Description: Reminders of the functionality. For
full details, refer to the MAX17048/MAX17049 IC
data sheet.
Write values to the device directly through the memory map. To write a raw hex value, select the cell in
the hex column, overwrite the value, and press the
Enter or Tab key. You are prompted to write to the
device. Normal communication pauses and you see a
corresponding blank spot in the graph.
For registers with a conversion factor (e.g. Hibernate
Threshold or VAlertMax), you can also modify the Value
column. The software converts the value back to the raw
hex and prompts you to verify that you are writing what
you expect.
Remember that not all registers are writable.
Plot
The plot can be configured using the Preferences window.
The plot is interactive. Zoom into the time axis by leftclicking and dragging anywhere in the plot area. While
dragging, the region becomes highlighted as you drag.
You can zoom out either by clicking the small button in
the bottom left, or by right-clicking in the plot area.
Plotted information not in a log file cannot be recovered
once the application closes.
The top and bottom plots are synchronized in time,
so zooming one zooms the other. The y-axes are
fixed scale and you cannot modify which registers are
plotted, or where.
Standalone Windows
Preferences
Here you can see options for how frequently you wish
to read the device and how to plot points. To observe
transient events, increase the read speed, as well as how
frequently the points are actually plotted.
The plots can use a lot of system memory if you read
frequently for a long time, so be aware of these settings.
After the maximum number of points is reached, points
are trimmed from the beginning. The discarded points
cannot be recovered on the plot.
I2C Traffic Log Window
Here you can see a log of traffic that you initiate, as well
as any time the device is programmed. It describes each
step in detail, including the particular values read or
written. This can help remove uncertainty about how to
communicate with the device. This log does not show the
standard reading events.
Memory Map Pop-Up Window
This window displays the same information as the memory map on the main application, except that values in this
map cannot be modified. This is the easiest place to read
descriptions of registers.
